One dumb question about the T bird, did it have A/C? If so, use those brackets, might have to use different hoses and might have to change pulleys or compressors since I think the switch to serpentine wasn't until '87...
If you use the stock turbo manifold and stuff yes it will work, how it lines up with the hood I have no idea, I have one but never installed it... a '86 wouldn't have an intercooler unless someone added an '87-88 unit on... if you're wondering on how it works without an intercooler it pings a lot under sustained boost at low altitudes and not that I condone such action but I just deal with it, the forged pistons have proven to me to be pretty resilient...
